To all whom it may concern: 7

Be it known that I, WILLIAM LAYMAN, a subject of the King of England, residing at West Fort Villiam, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improve ments in Grain- Car Doors and Locking Mechanism Therefor, of which the followiitg is a specification.

This invention has relation to certain new and useful improvements in grain car doors, and has for its primary object, the provision of a sectional door and a duplex locking znoch nism therefor.

A further object of the invention resides in the provision of an improved locking mechanism which may be operated only by a special form of key.

'Fvith the above and other objects in View, the invention resides in the novel construction, conib'nation, and arrangement of parts as hereinafter set forth in the specification, pointed out in the claims and shown in the drawings; in which Figure l is a view in front elevation of a car door constructed in accordance with my invention and locked in a closed position;

Fig. 2 is a vertical section on the plane of line 2-2 of Fig. 1, looking in. the direction indicated by the arrows;

Fig. 3 is an enlarged elevation of the locking mechanism;

Fig. i is a vertical section on the line -1-l of Fig. 3, looking in the direction indicated by the arrows;

Fig. 5 is an elevation of the lock case with the cover removed to show the opera tive parts of the lock in normal position;

Fig. 6 is a vertical transverse section through the lock case and the parts positioned in the same;

Fig. 7 is a sectional view on the plane of line 7-7 of Fig. 6, looking in the direction indcated by the arrow;

Fig. 8 is a perspective view of the lock case cover removed;

Fig. 9 is a detail perspective view of the slotted lever supporting plate;

Fig. 10 is a detail perspective View of one of the levers;

Fig. 11 is a detail perspective view of the lever supporting plate;

Fig. 12 is a detail perspective of one of the door section engaging members and the parts supporting the same; and

Fig. cciving cups carried by the door section.

Referring now more particularly to the drawings, wherein similar reference characters designate corresponding parts throughout the several views, 1 and 1 designate the channel bars at the opposite sides oi a door way of a grain car or the like, while 2 and 3 designate, respectively, the lower and upper door frame members.

A lower door section 4 is mounted to travel horizontally on the sill or lower doorframe member, while an upper door section 11 is mounted on the lower door section, as at 4', in Figs. 1 and 2, and is adapted to travel horizontally thereon. Then the door sections are moved rear of the channel bar 1; that is, they through an opening provided between the channel bar 1 and the body of the car.

The lower door section i and the upper door section 11 are provided, respectively, with cup bracketsor keepers 19 and-20 which are adapted to receive the free ends, respectively, of the pivoted door engaging members 21 and 22 to lock the door sections a and 11 in a closed position. The door engaging member 21 is carried at one end of a shaft 23, which has its central portion mounted in a suitable bearing 24 secured upon the inner edge of the channel bar 1.

At one end, shaft 23 is provided with a crank 23 that has connected thereto one end 01? aconnecting rod or operating member 25, the opposite end of which said rod is bifur cated, as at 26, and pivoted upon the operating lever 27. Upon reference to Fig. 12, it will be seen that upon movement of shaft 23, the locking member 21 will be moved in the arc of a circle whereby, upon entrance into the cup bracket 20,'the respective door section will be locked in a closed position.

Door engaging member 22 is carried by one end of a shaft 28, which is mounted in a corresponding bear" g 29 carried upon the 13 is a detail view of one 01" the re horizontally, they pass in inner edge of the channel bar 1, and the inner end of the shaft 28 has a crank 28' formed therefrom and connected with one 7 end of a connecting rod 30, as shown. The opposite end of connecting rod 30 1S pivoted to the laterally turned end of a connecting link or operating member 31, which latter is pivoted to the pin 32, projecting from one side of an operating lever 33, Levers 27 and 33 are pivotally mounted upon a shaft 34: h'avin bearin throiwh the ears 35' of the lever supporting plate 36, which latter 1s secured upon the outer face of the channel bar 1 and between the outwardly directed longitudinal edges of the same. It will be understood that the levers 27 and 33 are positioned between the ears 35, and that the .said levers 27 and 33 have enlarged and pointed ends or heads 37, preferably of rectangular form in cross section and provided with peripheral grooves 38 inwardly of the pointed ends or" the heads 37.

The grooves 38 are provided to permit theheads of said levers 27 and 33 to be engaged in the recesses or notches 39 formed 7 also cut away as at 41 in order to permit operation or red 30 (see Figs. 3 and 9). The

arms 414- also rest upon the cover l6 of the lock case 47 which latter has sliding more.

ment longitudinally between the arms 4i-l and the support 4:2, and the pointed ends of the 7 head 37 of the levers 27 and 33 will serve to limit downward movement of the lock case 17., The cover 46 has outwardly directed side flanges 48 through which any appropriate securing members may be extended to fasten said cover d6 upon the lock case 47, the secur ing members passing through the sides of the lock case 47. When the lock case 47 is in its lowermost position, the main oflset por-' tion. or" the U-shaped member 49, mounted upon the outer face of the cover l6, extends through the opening 50 in the hinged plate 45, previously mentioned, and bears against the outer faceof the latter to lock the same against the arms 44 and thereby prevent levers 33 and 27 from being withdrawn from the plate -l1. The hinged plate as is connected by a suitable hinge 51 to the dependedge 52 of plate 53, which latter has its opposite edge directed upwardly and. secured as shown at 5% to the channel bar 51. The plate 53 is provided with a suitable open.- ing 55 througl1 which extends the spring 56 havingone end connected with the upper end suitable openings being 'bers are provided W1 of the lock case 4-7, while, its other end is secured in a bracket arm 57, secured to the main portion of the channel bar 1, above the plate 53.7 Plate 53 may also be cutaway at a point in alinement with the cut away aortion 4-1 or plate ll, so as to permit ree operation of connecting link 30, isobvious.

The lock case 47 is locked in its lowermost position with the spring 56 under tension, by means of the outwardly directed bolts 58 which project through the sides of the lock case 47 and extend into openings provided for the same in the sides or" channel bar 1, provided for bolts 58, in the outer-edge of the side of the lock case 47 and the opposite edges of the cover 46, as will be readily recognized upon refer-ring to Figsri, 7, 8 and 10 of the drawings. v The bolts 58 have theirinner ends loosely mounted upon the upper diverging ends of the bar or bolt carrying members 59 which are pivoted, intermediate their opposite ends, upon therparallel post 60 projecting from the back of the lock'case 4:7. The diverging bolt carrying members 59are resiliently retained in the normal or locking position,'by means of the springs 61 which have their central portion coiled about an upper post 62, while their legs may be suitably secured to member 59, or at any other point. The bolt carryingmembers 59- are positioned outwardly'oi the outer ward. or ward plate 6 9 which is also mounted upon the supporting posts 60 and upon a lower supporting post 63. An inner ward or plate 64 is alsomounted upon the posts 60' and 63 and spaced from the back of the lock case +57. The inner plate 6% isfalso spaced from the intermediate spacing plate 6% and between the plates 64 and 6% are positioned the substantially parallel pivoted lock members ,(35 which are pivoted upon the'posts 60 and lee have their upper ends directed outwardly toward the opposed sides of the lock case 4?, a second spring 66 being provided to press against the lock members 65 and which serves to retain the inwardly directed lower ends 67' of themembers 65 in engagement with the opposite sides of the spacing block 63 in the lower end of the lock case 4-7. The spacing block 68'is secured to the'back of the lock case 47 and the cover 46 in a suitable manner, as shown at 69 in Fig. 6, and the extended end '70 of the spacing plate fi lis suitably secured to the spacing block 68. The lower ends 67 of the pivoted lock memh beveled shoulders 71 which are normally engaged with the rounded lower. end 72 of the bolt carrying members 59 to prevent 'operationof the latter without the use of the proper key 73', which is provided with opposite wings 74, for separating thelower onus of the lock members 65, while the parallel wings 75. (if ,key 73 separate the lower ends 72 of the boltany:

- mg members 59. It will also be seen that the proper form of key, is provided with recesses 7 6 and end wings 7 7 in order that the key may be rotated over suitable ribs or wards of ordinary construction (not shown).

From the foregoing, it will be readily seen that when the parts of the locking mechanism are in the position shown in Figs. 1, 8, at, 5 and 6, the lower door section 4 and the upper door section 11 will be securely locked in a closed position. However, upon insertion of the proper key 73, in the lock case 47, and turning the key, the bolts 58 will be drawn inwardly of the lock case 47, permitting the springs to act so as to draw upward the case 47 and thereby release the hinged plate 45 from engagement with the loop or detent 4:9 and permit the levers 27 and 33 to be engaged by the operator and swung out, so as to cause the operating members 25 and 31 to withdraw the door engaging members 21 and'22 out of engagement with the respective keepers 19 and 20.

The door sections 4 and 11 may then be moved horizontally, either simultaneously or selectively to an open position. When the door sections are again closed, they may be readily locked, by placing the levers 27 and 33 in position in the notches 39 of plate 41, thereby forcing the door engaging mem-' here 21 and 22 into the cup brackets or keepers l9 and :20, bringing the hinged plate 45 to position upon the arms 44 and drawing downwardly the lock case 47, while the bolts 58 will be automatically moved into the opening provided therefor in the sides of the channel bar 1.

While I do not wish to limit myself in any way, it is pointed out that the several securing members shown in Figs. 1 and 4.- may have their heads countersunk in respective plates or strips while the nuts or fastening members may be likewise positioned with respect to the door sections, thereby providing comparatively smooth surfaces which will permit of operation of the door members with greater ease.

lVhile the preferred embodiments of the invention have been shown and described, it will be understood that minor changes in the details of construction, and arrangement of parts may be resorted to within the scope of the appended claims without departing from the spirit of the invention or sacrificing any of the advantages of the same.
